PITTSBURGH (AP) - Gerald Gardner, a Pittsburgh scientist and social activist who helped end sex bias in newspaper want ads, died Saturday. He was 83.
He died of leukemia at a Pittsburgh hospital, said Gardner's wife, Jo Ann Evansgardner.
Gardner was a geophysicist who helped develop ways to use seismic vibrations to search for oil underground. But he was also an ardent feminist who used his math skills to develop statistics used in a landmark lawsuit against what was then The Pittsburgh Press newspaper.
As a result of that suit, the U.S. Supreme Court in 1973 essentially forbade newspapers from publishing separate want ads for male and female employees after Gardner developed statistics showing pay and other disparities females faced.
